Abstract
The utility model provides a kind of safe dual fail-safe heating kettle, its structure comprises the chassis being provided with heater circuit bottom water kettle body and water kettle body, key is also to comprise to be close to and is arranged on the first temperature sensor bottom water kettle body and is arranged on bottom water kettle body or the second temperature sensor of outside, also safety corridor is provided with in water kettle body, the entry position of safety corridor is higher than the setting safety injection liquid level of water kettle body, the outlet of safety corridor is connected to the second temperature sensor, first temperature sensor and the second temperature sensor are all connected with heater circuit.If utility model works principle is the first temperature sensor fails, water continues to boil, a large amount of vapours enters safety corridor, contacted with the second temperature sensor by safety corridor, second temperature sensor work, timely cut-out heater circuit, prevents security incident, greatly improves the security performance of heating kettle.
Description
Technical field
The utility model relates to small household appliances technical field, is specifically related to a kind of dual fail-safe heating kettle.
Background technology
Current heating kettle product is generally that a temperature sensor of connecting with heater circuit by arranging bottom heating kettle controls heater circuit break-make, when temperature bottom kettle reaches the temperature of this temperature sensor, this temperature sensor automatic shutdown circuit.And existing heating kettle product is mostly Quick heating kettle, because the large efficiency of power is high, water boils very soon.Once this sensor failure, heater circuit continues heating after water boil, the danger such as hot water boils, short circuit easily occurs, causes potential safety hazard.
Summary of the invention
The purpose of this utility model proposes a kind of safe dual fail-safe heating kettle.
According to the dual fail-safe heating kettle that the utility model provides, comprise the chassis being provided with heater circuit bottom water kettle body and water kettle body, key is also to comprise to be close to and is arranged on the first temperature sensor bottom water kettle body and is arranged on bottom water kettle body or the second temperature sensor of outside, also safety corridor is provided with in described water kettle body, the entry position of described safety corridor is higher than the setting safety injection liquid level of water kettle body, the outlet of described safety corridor is connected to described second temperature sensor, described first temperature sensor and the second temperature sensor are all connected with described heater circuit.
During dual fail-safe heating kettle work of the present utility model, when after water boil, as be that a temperature sensor of connecting with heater circuit by arranging bottom heating kettle controls heater circuit break-make, when temperature bottom kettle reaches the temperature of the first temperature sensor, first temperature sensor work, cut off heater circuit, if the first temperature sensor fails, water continues to boil, a large amount of vapours enters safety corridor, contacted with the second temperature sensor by safety corridor, second temperature sensor work, timely cut-out heater circuit, prevent security incident, the security performance of very big raising heating kettle.
Further, as preferred embodiment, described safety corridor is that described second temperature sensor is arranged on the bottom of water kettle body by the hollow pipe upwards suspended bottom water kettle body in water kettle body, install to facilitate and save space, facilitating circuit components layout.
Specifically, described temperature sensor is bimetal leaf kick switches.
Further, described chassis is connected with water kettle body one, to keep globality and the portability of water kettle body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As Fig. 1, dual fail-safe heating kettle of the present utility model, comprise the chassis 2 being provided with heater circuit bottom water kettle body 1 and water kettle body, also comprise and be close to the first temperature sensor 3 be arranged on bottom water kettle body 1 and the second temperature sensor 4 be arranged on bottom water kettle body 1, safety corridor 5 is also provided with in water kettle body 1, the entry position of safety corridor 5 is higher than the setting safety injection liquid level of water kettle body, the outlet of safety corridor 5 is connected to the second temperature sensor 4, first temperature sensor 3 and the second temperature sensor 4 is all connected with heater circuit.As preferred embodiment, safety corridor 5 is that the second temperature sensor 4 is arranged on the bottom of water kettle body 1 by the hollow pipe upwards suspended bottom water kettle body 1 in water kettle body 1, installs and saves space, facilitate circuit components layout to facilitate.The bimetal leaf kick switches that temperature sensor selectivity selected by the present embodiment is stable.For keeping globality and the portability of water kettle body, chassis 2 is connected with water kettle body 1 one.
